<H1>Software Development - U.S. Census Name Data Demo Program</H1>
<P>This program is designed to demonstrate a simple client/server program. 
A server program runs in the background, waiting for Name/Data requests.  When it receives a name request
it returns the matching data.
<P>  The reason for such a architecture is to allow a simple program, with a MAP preloaded with data,
to quickly provide results without incurring the overhead of a reloading the census data for each request.
